Isaac Levitan occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Isaac Levitan builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #AFAC74 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.7%). The palette spans 52 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 18 sits within the larger chromatic argument that Isaac Levitan's complete body of work advances.
